Subject: [PATCH 1/2] arm64: dts: uDPU: update partition table

Partition currently called "uboot" does not only contain U-boot, but
rather it contains TF-A, U-boot and U-boot environment.

So, to avoid accidentally deleting the U-boot environment which is
located at 0x180000 split the partition.

"uboot" is not the correct name as you can't boot these boards with U-boot
only, TF-A must be present as well, so rename the "uboot" partition to
"firmware".

While we are here, describe the NOR node as "spi-flash@0" instead of
"m25p80@0" which is the old SPI-NOR driver name.
